Abstract: An apparatus for displaying a television image on a television monitor applicable to a vehicle passenger compartment. In the television image displaying apparatus, the television monitor is installed on a center console of a vehicle passenger compartment. A liquid crystal filter is arranged on a television monitor screen which has variable transmittance according to a voltage applied across a whole surface electrode thereof. The liquid crystal filter serves to limit an angle of visible field around a driver's seat position with a front passenger seat position being provided a high image transmittance. In addition, a louver type filter is arranged between the TV monitor screen and liquid crystal filter. The louver type filter generally has a plurality of fine louvers, each elongate direction of the louvers being aligned in the horizontal direction.

Abstract: An optical filter is provided for suppressing unwanted reflections of background light when used with a display device such as a cathode ray tube or an electroluminescent screen, or in optical communication or surveillance. The filter has multiple thin layers including a first series of layers for suppressing reflections from its outer surface and a second series of layers constituting a bandpass interference filter. The first series of layers is arranged to suppress reflections over a broad wavelength band while the second series of layers allows transmittance over a relatively narrow wavelength passband within the broad wavelength band, resulting in improved contrast when the display is used in situations of high background light.

Abstract: A universal filter apparatus is described which provides, in a single unit, an anti-glare and/or anti-static screen and frame which is adaptable to monitors of varying sizes. The universal filter apparatus includes a filter screen mounted to a housing. The housing includes a front side, a top side, and at least two lateral sides, each of the at least two lateral sides extending perpendicularly from the front side. A elastically deformable nonresistant securing device is attached to each of the two lateral sides to allow the apparatus to be easily installed on monitors of varying sizes.

Abstract: A foldable screen protector for use on a computer monitor of various kinds has a fixing frame, a foldable top cover, and foldable left and right plates, thereof the fixing frame is adapted and secured to the screen of different types of computer monitors even to that of a notebook computer to provide the screen with protections against reflection of sunlight and oversight of others from outside; and by use of protruded tracks intersecting across the surface of the foldable top cover to reduce the amount of friction and a torsion spring, the foldable top cover and the foldable left and right plates can be folded and unfolded easily. When not in use, the foldable top cover can be folded up and lodged to the fixing frame as a protector to the screen.

Abstract: A multiplanar image display system having a plurality of display units disposed to expose, by transmission through and reflection by transparent panels, displayed images to a viewing end of an image chamber. The images overlap along a common viewing axis to create an illusion of a three-dimensional display. The transparent panels and a primary display unit are disposed along, and secondary display units are displaced from, the viewing axis. The transparent panels and the display units are angled to each other and to the viewing axis. The display units are adjustably mounted; and the distances separating the overlapping images, and thereby the amount of parallax, are controllable as a function of the distances between the display units and their associated reflecting transparent panels.

Abstract: A projection type display device including a CRT with a fluorescent layer and a face glass for projecting an image reflected onto the fluorescent layer through the face glass, a transparent liquid, at least one lens element and onto a screen. The transparent liquid is filled within a space between the face glass of the CRT and the at least one lens element and has a refractive index substantially the same as a refractive index of the face glass of the CRT and the at least one lens element. A light attenuation filter having a transmittance no greater than 0.9 is disposed at a position from the fluorescent layer to the at least one lens element such as between the face glass and the at least one lens element.

A formed angle .ltoreq.45.degree. of the fabric is horizontally against cathode ray tube. This screen-shielding method could suitably reduce glare and reflected lights, eliminate electrostatic charges and low frequency radiation, and prevent Moires and/or Newton Rings. This screen-shielding apparatus includes a frame, the high conductive fabric and a suitable ground wire, and is installed in front of the surface of the CRT.

Abstract: An antiglare/antistatic coating for a cathode ray tube (CRT) is applied to the outer surface of the CRT's faceplate and includes a first inner hygroscopic layer of silane, water, sulfuric acid and an alcohol mixture which may be applied by dipping, spinning or spraying. The coating further includes a second outer layer of silanes, water, acid, epoxy, and a coupling agent balanced with an alcohol mixture which is sprayed onto the first inner layer. The grounded first inner layer possesses high conductivity for antistatic protection, while the second outer layer, which possesses glass-like characteristics, provides antiglare protection by reducing the faceplate's reflectivity. The second outer layer dries as a hard porous coating which resists scratching and allows water vapor to penetrate into the first inner hygroscopic layer to maintain its high conductivity.

The optical film is a porous thin film made of fine magnesium fluoride particles and a binder containing a condensate of a silane compound having a fluoroalkyl group, a co-condensate of the silane compound and silicon, or a co-condensate of the silane compound and a metal oxide compound. The combination of the specific binder and fine magnesium fluoride particles permits forming a porous optical film having a surprisingly high mechanical strength, excellent resistance to humidity and reduced external light reflection from the display plane.
